Composite cable-About General Custom Cable Assembly

Cable manufacturComposite cableing outfitters have a far reach into many industries。 Making an impact on the medical， transportation， extreme sports， furniture， and other industries， custom cable assembly products are in high demand。 The following article relays basic information about custom cable assembly and cable stretch to better inform present and potential customers。

All wire rope and mechanical cables are made from individual wires twisted together into a strand。 Most small， commercial cables are crafted by starting with one core cable while a given number of additional cords are wrapped around this central cable。 The number of wires in a strand and the number of strands in cable manufacturing are dictated by the specified construction。

Some cables are designed to perform one function， while others are orchestratedCustom cable to address many， making every application unique and different。 Cable stretch is one factor consumers are interested in knowing about in relation to custom cable assembly。 There are two types of stretch - constructional and elastic。

All mechanical cables contain tiny clearances between individual wires and strands。 With the application of the initial load or trial， the clearance is minimized allowing the mechanical cable to stretch in length - this is constructional stretch。 A mechanical piece with more wires in its cross sectionMedical cable will stretch more during load or trial。

die casting machine-Die Casting and Casting Types

Casting is one oDie castingf the oldest procedures done on metals。 Many products are formed using this method。 Here is an attempt to share the knowledge of casting。
f four types: sand casting， permanent mold casting， plaster casting and Die casting。 All these types of castings have their own advantages and disadvantages。 Depending on the properties of the product requited， one of the casting is selected。

Sand Casting: Sand casting is the oldest casting of the above。 ThisMulti slider die casting machine method of casting is in use since 1950。The texture of theMulti slider die casting machine product depends on the sand used for casting。 The end product is given smooth finishing at the end。 Usually iron， steel， bronze， brass， aluminium， magnesium alloys which often include lead， tin， and zinc are used。

Permanent mold casting: Permanent mold casting uses two pieces of mold。 This molds are joined together and molten metal is pored into this moldzinc die casting。 The hot metal is allowed to cool and the mold pieces are separated。 Some products have metal extrusion which are removed by flash grind or by hand。 Tin， lead anddie casting machine Zinc are commonly moulded using this method。

Plaster casting: Plaster casting is one of the easiest methods。 How ever it is used for metals with low melting point like Coper， Zinc and Aluminum。 This isdie casting machine the easiest process because mold can be made easily in case it brakes in the procedures。

: Die casting is done by introducing molten metal into the mold at high or low pressure。 Earlier only low-pressure diezinc die casting-casting was used but now a days high pressure die casting is used more extensively。 Molds are well designed to give complex products with stunning accuracy and smooth finishing。 They are made of high quality steel as steel has higher melting point。 These molds can be reused thousands of times。 Casts can be single cavity that produces only a single component， multiple cavity that produces multiple identical parts at a time， unit die that produces different parts and combination die that produces different parts in one go。 Usually zinc， copper， aluminium， magnesium， lead， pewter and tin based alloys are used for die casting。

Custom Mold Rubber Parts-Comparison of O-Ring Materials

While selecting Rubber Sealan O-ring for your application， a lot of importance should be placed on the material of the seal being used。 Since a proper sealing action is highly dependent on the condition of your O-ring， it is important that an O-ring material be chosen to best suit the operating environment of your application。 Some of the common materials used to make O-rings are nitrile rubber or Buna-N， Viton(r)， silicone rubber， neoprene， and PTFE or Teflon(r)。

Choosing an O-ring material is dependent on a number of different factors， but two of the most critical factors are the operating temperature range thatRubber O-Ring O-rings are subjected to and the different chemicals they may be exposed to。 Some additional factors that play a role in the selectionRubber Parts of an O-ring material include resistance to tearing and abrasion， and sunlight or aging。 Since most O-ring materials react differently to diverse environments as well as chemicals， each material has its own advantages and disadvantages。

Nitrile Rubber:

One of the most common materials used to make O-rings is nitrile rubber or Buna-N， which is a synthetic rubber copolymer。 This material has excellent resistance to water， hydraulic fluids， solvents， oils and other petroleum products。 This feature， coupled with its operating temperature range of between -65 degrees F to +275 degrees F， has made nitrile rubber one of the most widely used elastomers to make O-ring seals。 However， this material does have its limitations； nitrile is generally not recommended forCustom Mold Rubber Parts applications where it might be exposed to sunlight and ozone， as well as certain chemicals， which include ketones， esters， and aromatic hydrocarbons。 Furthermore， its susceptibility to ozone also makes it necessary that nitrile rubber seals are not stored near electric motors that normally generate ozone。 Its high resistance to petroleum products and reasonable resistance to temperature has led to Nitrile rubber O-rings becoming the first choice for various applications in the automobile industry。

Silicone Rubber:

Silicone rubbers are a collection of elastomeric polymers produced from silicon， hydrogen， oxygen， and carbon。 Silicones generally have poor resistance to abrasion and tearing， as well as low tensile strength plus high co-efficient of friction - features that make them unsuitable for dynamic sealing applications。 However， its exceptional resistance to extreme temperatures，Rubber Gasket ranging from as low as -150 degrees F to as high as +500 degrees F， makes it ideal for applications where seals are exposed to high dry heats， as in automotive components and cookware。

Viton(r):

Viton(r) is another synthetic rubber commonly used for making O-ring seals， which is a type of FKM elastomer。 This elastomer´s excellent resistance to solvents and oils， as well as its resistance to broad operating temperature ranges， has made it a popular for use in a number of applications。 Though its operating temperature ranges from -10 to +400 degrees F， seals made from this material are known to withstand temperatures as high as +600 degrees F for short times。 This combination of properties makes Viton an ideal choice for high temperature applications as well as applications exposed to a variety of different fluids。 One such application that has adopted Viton O-rings is SCUBA diving， where the O-ring seals are used in the diver´s air tank。 However， though Viton is compatible with most hydrocarbons， it is generally not compatible with ketones and organic acids。

PTFE:

One fluoropolymer commonly used to manufacture O-rings is PTFE， or Teflon(r)， as it is commonly known。 PTFE is one of the most chemically inert materials used to make O-rings and extremely resistant to oils， solvents， bases， acids， steam， and various other chemicals。 Its unparalleled resistance to abrasion and tearing makes it ideal for dynamic sealing applications。 However， there are few drawbacks to using PTFE O-rings。 The first one is their inability to be compressed as effectively as other commonly used O-ring materials， which translates into inefficient sealing。 The other major disadvantage of this material is its poor cold flow characteristics under constant strain。 Still， its chemical resistance and low coefficient of friction has made it a popular sealing option in many valves and other applications。

Video wall-What is the Best Mini Media Center?

Today I will tryIP66 to answer a question posted on the title of this article。 It is not easy to give a simple and short answer as it really depend what is parameters may be most important to you。 Some of people may want a small form factor computer。 Some of other may want a fanless and completely silent media box。 And some of other may want to get best possible quality of movies they watch。 I will try to satisfy all of given typespanel PC of people。 I will start from first of these needs。

Small form factor HTPC?

First of points given on the beginning of this article I have told that many of you may want a small form factor computer。 Moreover I have evendigital signage put it in the article title。 Why it may be so important? Because no oneFanless pc want a huge computer standing near their high class Full HD TV。 It do not look good。 Much better are little media centers or even these that are invisible (VESA Mounted)。 It is why we will choose a Mini-ITX form factor computer。 It can look really good in a small computer chassis or be hidden on the back ofsunlight readable your TV。

Shouldtouch screen monitor it be fanless?

You may ask what is a difference between fanless and traditional PC? It is huge difference！ When you watchIndustrial pc a great movie you really do not want to hear your computer。 It may really disturb you and make watching movies a really bad experience。 Some of people never watch anything on their HTPC as it is too loud！ Even if itIndustrial monitor won´t be fanless it should be very quiet！

Do you need Full HD playback。。。?

Yes you do！ More and more movies are coming in Full HD 1080p quality and in next year or two 100% of new movies will be available only in thisVideo wall format。 It is why you want a media center capable to play it！ So it should have powerful CPU (but it would not be fanless then) or some movie hardware decoder on board。 Currently most popular are NVIDIA ION based mini motherboard that can easily decode FullBox PC HD stream without CPU usage。

So what to choose?

On the beginning of this article my head was full of ideas for a media center to recommend。 But after considering these 3 points I can recommend only one mini media center。 In this place I really recommend a ZOTAC MAG！ It is small and have very elegant look or can be mounted on back of your TV。 It have fanless one core version。 And itAll in one computer have ION chipset on board！ Moreover it can be easily customized as it have no HDD nor RAM when you buy it。 You may put as big disk and as much memory as you need。 Have better recommendation。。? Please share in the comments。

powder metal-Introduction to Metal Injection Molding

Metal injection sintered metalmolding is a technique of making metallic parts， which makes use of the process of powder metallurgy。 Though the process uses metals in powdered form， it is unlike the usual powder metal dispensation。 Metal injection molding requires metallic powders to be ten to hundred times smaller in size， compared to powder metal processes。 The final product in case of metal injection molding has a higher density。 The features and benefits of metal injection molding are comparable to that of rubber and plastic molding， but the final product you get is much stronger。 This technique is often used for producing surgical tools， components of firearms， hard disk drives for computers， electrical connectors and automotive locks。

Process of Metal Injection Molding

This process comprises of five steps， which include the mixing， the injection molding， the de-binding， the sintering and the part finishing。 This process is becoming more popular by the day。

The first step involves the mixing of metallic powders， which are known to be strong and have inherent characteristics， like high impact strength， wear resistance， hardness， machine ability and temperature characteristics。 The binding agent is also added at this stage。 The purpose of mixing different metallic powders is to derive a metallic compound that has all the positive characteristics of different metals， while eliminating their respective weaknesses。

As a result of the mixing of powders， we get what is known as feedstock， which is injected into the desired molds， as it is done in the case of rubber or plastic moldings。 The component that we get as a result of molding is called as green part。

The de-binding stage involves the immersion of the green part in water baths to get rid of the binder that has gone in the part matrix。 During cross linking， the de-bounded green component is subjected to ultraviolet light， resulting to a thermo setting of the binding agents that were used among the metallic powders。

After the binding stage is over， the component is heated to a temperature of above 2000 º Fahrenheit in a furnace。 This process is known as sintering， and it fuses the metallic parts to give them a solid shape。 At the end， the sinteredsintered metal components are delivered to the finishing stage for eliminating the imperfections and burrs。 The component is now ready for dispatch。
